논문초록 This research introduces the fabrication of polymer particles with sophisticated structures for the high immobilization of Au nanoparticles (NPs). The procedure involves the use of cationic extra monomer to synthesize solid polystyrene (PS) beads with cationic property, followed by their transformation to complex-structured particles via the phase separation route in a seeded dispersion polymerization. Control in the phase separation enables us to obtain PS particles with cage and bowl-like shapes as well as hollow structure. The large surface areas of the complex-structured particles, as theoretically calculated using simple models, and the electrostatic attraction between the negative charged noble-metal NPs and them, as experimentally observed, allow the high immobilization of the noble-metal NPs on their surfaces.
